Iranian parliament speaker Mohammed Baqer Qalibaf said Iran must prepare to overcome what he called unjust sanctions, a day after U.S. Treasury Secretary Scott Bessent announced measures he described as the toughest ever imposed on Iran. Bessent said the sanctions would be detailed on Monday, suggesting they could reduce the need for further major military operations. Qalibaf, one of Iran’s most influential political figures and Tehran’s top negotiator in talks with the United States, said economic development and security were closely connected. He accused the United States and Israel of waging economic and cognitive warfare after concluding they could not prevail in a direct military confrontation with Iran and Iraq. Speaking to Iranian and Iraqi business representatives in Baghdad, Qalibaf called for stronger economic ties between Baghdad and Tehran and said the countries could use their national currencies in trade to reduce reliance on the U.S. dollar.
